Final answer:
When handling an unjustified customer complaint, it is important to listen, provide evidence or explanation, and offer solutions or compromises if necessary.
Step-by-step explanation:
When handling a customer complaint that I deemed unjustified, I approached the situation in a professional manner. First, I listened to the customer's complaint and empathized with their concerns.
Then, I calmly explained the company's policy or procedure that was being questioned, providing any necessary evidence or examples to support my response. Finally, I offered alternative solutions or compromises, if applicable, to address the customer's concerns and maintain customer satisfaction.
